Do you remember the movie Alita: War Angel? It is Hollywood's latest attempt to adapt

Japanese comics after Dragon Ball and Ghost in the Shell, and arguably the most

thoughtful. Project promoter Cameron has been grinding a sword for ten years, and

finally used this "Yuan Zuozhuan" science fiction comic book to ignite the audience's

vision.

"Battle Angel" Alita's most central and attractive piece of equipment is her mecha. In the

movie, the Berserker mech is a armor created by Mars 300 years ago in order to better

use mech, which can adjust details such as gender and shape through brain memory.

This kind of material that can change the shape of the mind is not just black technology. Do the high-tech nano-materials on the heroine's body really exist in modern society? Other than traveling to the future, is there any way to get this technological experience?

Automatic patching technique

Penn State University has developed a new high-tech nano-repair material called Nano

Cure Tech (Automatic repair technology). It achieves its function by covering the surface

with a PET (polyethylene terephthalate) coating with high viscosity, elasticity and

buffering properties.

This fabric brings friction and heat through the rubbing of the fingers, the damaged

structure between the molecules is reconstructed under the action of friction and heat,

and the fracture of the fiber will be automatically connected, and the material has good

waterproof performance, and the automatic repair performance will not be affected in

the case of sweat.

However, the material is currently only very effective at repairing holes the size of a finger, which means that if the damage is too large, it may not be able to repair conditions.

Temperature control technology

Textile people in high-tech fabrics on the "temperature" research has not been a year or two, at present, warm fabrics and cool fabrics are not rare in the market, but there has not been a change in their own thermal insulation due to environmental changes.

Researchers at the University of Maryland have developed a fabric that automatically adjusts to control the heat that passes through it. The researchers created the fabric using functional yarn coated with conductive material. In hot, humid conditions, the yarn bundles tighten and activate the coating, changing the way the fabric interacts with infrared radiation.

The fibers made into modified yarns are composed of two different synthetic materials, one absorbent and the other hydrophobic. The yarn is coated with a carbon nanotube coating, which is a special lightweight carbon-based conductive material. Because the fiber material is both water-absorbing and hydrophobic, when it is exposed to moisture (such as around a sweating human body), the fiber bends and deforms, tightening the yarn bundle. This widens the voids in the fabric, changing the electromagnetic coupling between the carbon nanotubes in the coating while promoting heat dissipation.

Smart basketball shoes

Nike's Adapt BB basketball shoes can automatically tie the LACES by adjusting the tightness of the upper through a mobile APP or two buttons on the shoe.

The shoes come with a Flyknit upper and a QuadFit mesh material inside boot. In order

to ensure that the midsole black technology FitAdapt has enough room to show itself,

the midsole does not use any cushioning technology, just equipped with Cushlon foam.

The core equipment of this pair of automatic lacing basketball shoes, it contains the

battery, gyroscope, controller, Bluetooth, measurement module and other devices.

Visual effects are constantly upgrading, the use of science and technology in people's

lives will be more and more extensive, and the intelligent life presented in modern

science fiction movies may not be far away from us.
